Jacobs Engines - Part 1 - Differences between models

Learn from Steve Curry, President of Radial Engines Limited, about the differences, similarities and maintenance for the r-755 and r-915 series Jacobs engine models. These models were produced from the mid-1930s to the mid-1950s. In this video series, you will see all you need to know about the 25-hour inspection, cylinder replacement, ignition systems and how to avoid liquid locks, break in your new engine and modify the original manufacturer's tools so that they work in the real world.
Steve touches on the horsepower, displacement and the differences in cylinders on l4 and l6 models. You will discover the small differentiations between engines and improvements Jacobs has made over the years. Steve will explain the meaning behind the suffixes and prefixes for the engines, the contributions Jacobs made for the aircraft industry as a whole, the material differences and much more.

Excellent explanation of all the subtle differences between the post war engine models.

I don't know how old this video is, (it's obviously video tape.) But this man is (was) a guru of the Jacobs engine.

Steve still is!

The Dell in the background in the beginning would put it sometime after ~2005.

Hello! I have a Jacob's R-915 that I would like to see find a good home. How can I get in direct contact with you?

[@lifuranph.d.9440]

I got my A&E [not A&P] in 1969, one of the last few.

[@radialengines6980]

That was just a few years ago.

Maybe it will work now? The RUclips engine has to transcode to different formats.
